U.S. Support for Israel's Nuke Policy Eroding - Herb Keinon
Cracks are appearing in the nearly half-century U.S. policy of upholding Israel's right to maintain its "nuclear ambiguity," as Israeli nuclear capabilities are, for the first time, scheduled to be on the IAEA agenda. One diplomatic official said that the U.S. has relayed messages to Israel that it will not let its nuclear position be harmed, but in the past the U.S. killed such discussions in international forums, while this time it failed to do so.
Emily Landau, a senior research fellow at the Institute for National Security Studies at Tel Aviv University and director of its arms control and regional security program, said the U.S. was not assuming its role as the shield of Israel's nuclear capabilities to the degree it had in the past. Obama, according to Landau, has embraced the agenda of nuclear disarmament, as well as the norm of "equality" that is embedded in the NPT, meaning that all countries should be treated equally on the nuclear issue.
